4] Reset Update Components

Whenever you install a cumulative update or feature update on your computer, a little info about the update gets saved inside SoftwareDistribution and catroot2 folders. When the data inside either of these two folders become excessively large, they start causing problems updating Windows. In order to resolve this issue, one must purge both folders.

As the update services are already running in the background, make sure to stop them first. Let’s learn how to reset update components in Windows 11/10 –

  • Press Win + R to launch the Run dialog.
  • Type “CMD”, and press Ctrl + Shift + Enter keys altogether.
  • Ideally, the UAC prompt will appear next, hit Yes to authorize accessing Command Prompt as admin.
  • On the elevated console, execute the below codes to stop essential update-related services.

net stop bits

net stop wuauserv

net stop appidsvc

net stop cryptsvc

  • Now that you have stopped updating services, rename the Windows cache folders by running these two codes –

rmdir %systemroot%\SoftwareDistribution /S /Q

rmdir %systemroot%\system32\catroot2 /S /Q

Note: After you rename a folder, a separate folder with its original name gets created at its specific location. You may visit C:\Windows & C:\Windows\System32, and notice the same.

  • Restart all the services that you have stopped prior to renaming cache folders. To do this, copy/paste the below code and press Enter separately.

net start bits

net start wuauserv

net start appidsvc

net start cryptsvc

  • Restart your PC next and check if you can update Windows now without getting into an error code 0x800706b5.
